Abstract:
An epicyclic gear system (A) includes a sun gear (2), a ring gear (4) located around the sun gear, planet gears (6) organized in two arrays between the sun and ring gears, and a carrier (8) having walls (14) located beyond the planet gears and flexpins (24) that project from the walls into the planet gears. Each flexpin includes an inner pin (30) provided with a flange 36 that is secured to the wall from which the inner pin projects, thus cantilevering the inner pin from the wall, and a sleeve (32) that is cantilevered from the opposite end of the inner pin and extends back over the inner pin, thus providing a double cantilever. Between the sleeve of the flexpin and the planet gear for that flexpin is a double row tapered roller bearing (26). The planet gears on the one array may be offset angularly with respect to the planet gears of the other array.
